IMPROVEMENT IN DEVICES FdR STEA MING OIL-WELLS.-

Specification forming part of Letters Patent No. 139,656, dated June 10,1873; application filed August 27, 1672.

.To all whom 2;; may concern:

Be it known that I, THOMAS E. CAROTHERS, of Oil City, County of Venan goand State of Pennsylvania, have invented a new and useful Improvement inDevice for Steaming Oil- Wells; and I do hereby declare that the fo1-lowing is a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawing makingpart of this specification, and to the letters and figures of referencemarked thereon.

The figure on the drawing represents a vertical section of theinvention.

My invention relates to an improved device for steaming oil-wells,,andconsists in introducing, within the casing and outside of the tubing, anadditional pipe to extend below the tubing, said pipe being perforatedabout two or three'feet above the bottom of the well,

the perforations continuing up to near the top of the sand-rock. Steamfrom a steamchest is forced down through the perforated pipe, therebymelting and clearing out from the oil veins or crevices all theparaffine and other extraneous matter clogging them, thus supplied withsteam from a-steam-chest the supply can be regulated at the will of anattendant by means of a cock in the pipe. a a a, a representperforations in said pipe.

Steam from the boiler passes through a sup ply-pipe to a steam-chest;from thence to the pipe for steaming the well, said pipe extendin g downthrough casing-head to the bottom of the well, the steam-pipe beingperforated about two or three feet above the bottom, said perforationsextending upwardly to near the top of the sand-rock. Jets of steamescaping through perforations in the pipe tend to melt and clear the oilveins or crevices from parafiine or other extraneous matter, thereby.
